Referring to FIG. 4, the search service providing apparatus 100 according to an exemplary embodiment may provide an initial search result corresponding to an initial search word input from the user terminal 200 to the user terminal 200. In addition, the search service providing apparatus 100 may provide the user terminal 200 with additional search terms determined based on the initial search term and additional search results corresponding to some additional search terms among the additional search terms.

The search service providing apparatus 100 may provide an initial search result for an initial search term to the user terminal 200. For example, as shown in FIG. 4, a case where the first initial search word 170 of 'dizziness' is received from the user terminal 200 may be considered. In this case, the control unit 120 of the search service providing apparatus 100 may provide the user terminal 200 with a search result corresponding to the “dizziness” that is the first initial search term 170, that is, the first initial search result 172. can do. The first initial search result 172 may include a definition of dizziness, a cause of dizziness, or text including the word dizziness.

In this case, the first initial search result 172 may be data selected from information or answers stored in the answer database 162. Through this, the search service providing apparatus 100 may provide an answer to a search word currently received from the user terminal 200 by using data received in the past from the user terminals 200.

The search service providing apparatus 100 may determine one or more additional search terms based on the received initial search word. For example, as illustrated in FIG. 4, the control unit 120 of the search service providing apparatus 100 may have symptoms of dizziness that may cause dizziness in relation to the initial search term “meniere disease” or “pruning”. Neuritis ”,“ positive paresis ”, or“ stroke ”may be determined as the first additional search terms 174.

In this case, the first additional search terms 174 may be data selected from search terms or questions stored in the search term database 161. In addition, the first additional search terms 174 may be data stored as being associated with the first initial search word 170 in the search word database 161. The data stored as being relevant may be search terms or questions searched before and after searching for the first initial search term 170. For example, the content searched before or after searching for the first initial search word 170 may include a phenomenon or an event that causes the first initial search word 170, a phenomenon or an event that is a result of the first initial search word 170, or the first. This is because, when the same thing as the initial search word 170 occurs, the probability of a phenomenon or an event that may occur together is high. In this way, the search service providing apparatus 100 may determine the first additional search terms 174 that are highly related to the first initial search word 170.

In addition, when the search service providing apparatus 100 selects additional search terms from among search terms or questions stored in the search term database 161, the search service providing apparatus 100 may consider information about a user who inputs the search terms or questions. For example, with regard to 'dizziness', a specialist with medical expertise, such as a doctor or pharmacist, entered the search term 'meniere' and a non-medical person entered the search term 'cold'. I can think of it. In this case, the controller 120 of the search service providing apparatus 100 may determine the additional search word by prioritizing the search word input by the expert over the search word input by the general public. Information about such a user may be stored in a user database included in the database 160.

The search service providing apparatus 100 may determine the rank between the determined additional search words.

In this case, the controller 120 of the search service providing apparatus 100 may determine the rank between the search terms in the order in which the number of answers corresponding to each of the additional search terms is included in the answer database 162. For example, 'mennier's disease', 'vestibular neuritis', 'positive paroxysmal gynecology', and 'stroke' were selected as the first additional search terms 174, among which the number of answers related to 'mennier's disease' was selected. If more than the number of answers associated with other additional search terms, 'Ménière's disease' may be determined as the first priority.

In addition, the controller 120 of the search service providing apparatus 100 may rank the additional search terms in the order in which the number of answers written by experts in the field related to the answer among the corresponding corresponding search terms is included in a large number. You can decide.

In addition, the control unit 120 of the search service providing apparatus 100 utilizes statistical data and the like that exist in the database 160 to generate a number of occurrences of facts corresponding to each of the additional search terms for a predetermined period and an initial search term for a predetermined period. Information about the number of facts corresponding to each of the additional search terms and the number of facts corresponding to each of the additional search terms or the facts corresponding to the initial search word may occur. Thereafter, the controller 120 of the search service providing apparatus 100 may determine a higher ranking of additional search terms having a high statistical occurrence probability or a high occurrence frequency.

In addition, the control unit 120 of the search service providing apparatus 100 may include an age, a gender, a job, an address, a field of interest, a field of information input in the past, and a field of information input in the past. Information about a field of search terms, a field of questions input in the past, or a field of answers input in the past may be checked. Subsequently, the controller 120 of the apparatus 100 for providing a search service may determine the ranking of additional search terms in order of the number of searches by other users having the same or similar personal information as the corresponding user.

In addition, the control unit 120 of the search service providing apparatus 100 may search for additional search terms of each user using the search service providing apparatus 100 for a predetermined period of time, or additional search results corresponding to each of the additional search terms. Consider the average reading time for. Thereafter, the control unit 120 of the search service providing apparatus 100 may search for the additional search terms in the order of high number of search or in order of the average reading time of the additional search results corresponding to each of the additional search terms. The ranking of additional search terms may be determined.

As described above, when determining the ranking between the additional search terms, the number of answers corresponding to each of the additional search terms, the probability that each of the additional search terms occurs, information about the user who entered the initial search query, or the satisfaction of past users, etc. In consideration of this, additional search terms having a high probability or importance may be determined. Through this, the search service providing apparatus 100 may provide additional search terms having a higher probability of being helpful to the user of the search service at a higher rank.

The search service providing apparatus 100 may select some additional search terms from among all the additional search terms in the order of high ranking. Thereafter, the search service providing apparatus 100 may provide additional search results corresponding to the selected additional search terms to the user terminal 200. For example, as shown in FIG. 4, 'Ménière's disease', 'Vestibular neuritis', 'positive paroxysmal gynecology', and 'stroke' are selected as the first additional search terms 174, and among these, 'Menny' You can think of the case where the disease is ranked in the highest ranking. In this case, the control unit 120 of the search service providing apparatus 100 may compare the first initial search result 172 and the first additional search terms 174 with only the first additional search result 176 for the Meniere disease. The user terminal 200 may be provided together.

In this case, the first additional search result 176 may be data selected from information or answers stored in the answer database 162. In this way, the search service providing apparatus 100 may provide an answer to an additional search word from the user terminal 200 by using data received in the past from the user terminals 200.

The search service providing apparatus 100 may receive feedback of the evaluation from the user terminal 200 with respect to the additional search terms and the additional search results provided. That is, the evaluation results of the satisfaction of the additional search terms and the additional search results from the user's point of view of the search service, the evaluation of the accuracy or satisfaction of the additional search terms and additional search results of the search service providing apparatus 100 The input receiver 110 may receive an input from the user terminal 200. Thereafter, the controller 120 of the search service providing apparatus 100 may be used in a process of selecting additional search terms or a ranking of additional search terms based on evaluation contents such as accuracy or satisfaction received.

Referring to FIG. 5, when the search service providing apparatus 100 receives a search word written in a natural language form from the user terminal 200, the search service providing apparatus 100 may determine the initial search word by determining a specific noun from the natural language. In detail, the input receiving unit 110 of the search service providing apparatus 100 may receive a natural search word consisting of a noun, a pronoun, an investigation, a verb, an adjective, an adjective, an adverb, an investigation, or an interjection. In this case, the controller 120 of the search service providing apparatus 100 may determine an initial search word by selecting a word included in the natural search word or determining a noun from parts of speech of the natural search word.

For example, as shown in FIG. 5A, a case where the first natural search word 178 of 'head is thin' is input from the user terminal 200 may be considered. In this case, the controller 120 of the search service providing apparatus 100 may grasp the fact that the 'head' is in a state from the noun 'head' and the investigation of 'ga'. In addition, the control unit 120 of the search service providing apparatus 100 is a sentence that means the state that the head is '띵' the natural language 'head' is a '띵' from the noun '띵' and the verb 'hae' In this case, the initial search term 'dizziness' may be determined.
